WILFRED J. LE VIE, OF LOS ANGELES, CALIFORNIA.

ADVERTISING DEVICE.

Application filed August 5, 1920. Serial No. 401,511.

To all whom it may concern:

Be it known that I, WILFRED J. LE VIE, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia have invented new and useful Improvements in AdvertisingDevices, of which the following is a specification.

This invention relates to advertising devices and has for its object theprovision of a greatly simplified construction whereby an illuminatedsign may be automatically, repeatedly displayed, the power for actuatingthe sign mechanism being derived from the heat of the illuminating meansso that a device inexpensive to operate is provided.

' e invention will be readily understood from the following descri tionof the accompanying drawings, in w 'ch- Figure 1 is a vertical sectionthrough an advertising device constructed in accordance with theinvention.

Fig. 2 is a horizontal section on the line 22 of Fig. 3.

Fig. 3 is a front elevation of the device partly broken away. casing isshown at 1, preferably, rectangular, said casing bein provided at itsopen front end 2 with a rame 3 which is, preferably, laterally removablefrom the casing through a slot 4. The frame 3 is adapted to carry asheet of suitable transparent or translucent material 5 adapted to'close the front open end of easing 1.

The mechanism within the casing is, preferably, supported upon a falsebottom 6. A support 7 is mounted upon the false bottom 6 and anincandescent electric lamp 8 is mounted uponthis support by means of ausual lamp socket 9.

- The sign to be displayed is carried upon a drum fitting over the lamp8 and arranged to rotate so that a changeable sign will be repeatedlydisplayed. The drum consists of spaced annular rings 10 supporting thecylinder 11. The cylinder is of transparent material such as isinglass,and the surface thereof is suitably decorated or lettered by means of anopaque material such as'lamp black in order to form a desired displaysign when the cylinder is illuminated by lam 8.

The upper ring 10 forms a s p1 or 12 extending across the top of thedisplay drum,

. said spider being formed by tproviding a disc the drum and extendingacross the top 0 (1180 into subbending portions 13 ofsaid interiorsurface of stantially longitudinal alinement with the drum 1 n order toprovide propeller blades. 11 earing cap 14 is provided at the center ofspider 12 extending axially beyond the same,

and said bearing cap is arranged to receive a pivot pin projectingupwardly from lamp 8 1n order to provide a pivotal support for thedisplay drum. The pivot pin is, preferably, formed from a wire bent toform a drum may be controlled by adjusting the an- 7 gular dispositionof blades 13. In order to complete the draft thus formed through drum11, apertures 18 are, preferably, provided in the top of easing 1 abovethe lamp and drum, and said apertures may be cov- 8 ered'by a lightshield 19.

The illuminated sign thus formed by display drum 11 is adapted to beprojected upon the sheet 5 forming the display surface of the same. Forth' able lens is mounted between the drum and sheet 5 and is, prefera'blable relative to the display drum ing the sign upon instance of this isprovided upon support 7 in" front of the lamp and display drum and apedestal 21 is longitudinally slidable along bracket 20. A screw rod 22is threaded through pedestal 21 and is journaled in bracket turning theknurled head 23 of said rod the pedestal will be adjusted lengthwise ofbracket 20 and toward and away from the display drum 11. A sleeve 24 ismounted dis lay ad iistor focusthe display sheet 5. As an upon pedestal21 and is longitudinally ad- 100 justable relative thereto by means ofsaid screw 25. The sleeve carries a mounting 26 in which is supported alens 27.

The interior of the casing forming the. device is, preferably, which maybe formed by suitably coat-in the the casing as with amp black. Asaconsequcnce when the lamp 8 is illuminated and the display drum rotatedthe light shining through will be )rojected through lens 27 againstdisplay s set 5 and an illuminated sign will.

is illuminated the heat 1s purpose a, suitarrangement a bracket 20 20 sothat by a non-reflecting surface the display drum 11o as aconsequence'be displayed upon the display sheet of the device.

Various changes may be made without departing from the spirit of theinvention as claimed.

What is claimed is:

1. In a display device, an electric lamp, a yoke detachably applied tosaid lamp, a pivot pin projecting upwardly from said yoke, a transparentmember disposed about said electric lamp, a bearing cap in the top ofsaid member which bearing cap receives the pivot point of the yoke,blades projecting upwardly from the top of said transparent member whichblades are adapted to be impinged by currents of heated air arising fromsaid lamp and thereby imparting r0- tary motion to said transparentmember, a screen, a lens between said transparent member andsaid screen,a standard for said lens, a guideway having said standard slidabletherein, and a screw rod engaging said standard to adjust the positionof said lens with respect to said transparent member and said screen.

2. As an article of manufacture, an advertisin device comprising, incombination, a box lire chamber substantially closed on all sides andhaving a front window provided with a translucent screen member, anupright electric bulb arranged in the rear of the chamber, a sign mediumconsisting of a rotatable drum surrounding the bulb and provided withmeans whereby it is rotated by the energy of heat when the bulb isenergized, and means in the chamber carrying a lens disposed between thesaid medium and the screen and whereby said lens may be shifted toproperly focus the image cast upon the screen, mounted u on andsupported by the said electric bul In testimony whereof I have signed myname to this specification.
